About this game

DuckStation is an simulator/emulator of the Sony PlayStation(TM) / PSX / PS1 console, focusing on playability, speed, and long-term maintainability. The goal is to be as accurate as possible while maintaining high performance.

A "BIOS" ROM image is required to start the emulator and to play games. A ROM image is not provided with the emulator for legal reasons, you should dump this from your own console using Caetla or other means. These are usually dumped as "scphNNNN.bin" or "ps-NNN.bin", where NNNN is the model number or ROM version, and should be 512KB in size. Games are NOT provided with the emulator, it can only be used to play legally purchased and dumped games.

DuckStation supports cue, iso, img, ecm, mds, chd, and unencrypted PBP game images. If your games are in other formats, you will need to convert or re-dump them. For single track games in bin format, you can use to generate cue files.

Features include:
- OpenGL, Vulkan (recommended) and software rendering
- Upscaling, texture filtering, and true colour (24-bit) in hardware renderers
- Widescreen rendering in supported games (no stretching!)
- PGXP for geometry precision, texture correction, and depth buffer emulation (fixes texture "wobble"/polygon fighting)
- Adaptive downsampling filter
- 60fps in PAL games where supported
- Per-game settings (set enhancements and controller mapping for each game individually)
- Up to 8 controllers in supported game with multitap
- Controller and keyboard binding (+vibration for controllers)
- RetroAchievements in supported games (
- Memory card editor (move saves, import gme/mcr/mc/mcd)
- Built in patch code database
- Save states with preview screenshots
- Blazing fast turbo speeds in mid to high end devices
- Emulated CPU overclocking to improve FPS in games
- Rewinding (do not use on slow devices)
- Controller layout editing and scaling (in pause menu)

DuckStation supports both 32-bit/64-bit ARM, and 64-bit x86 devices. However, due to it being a more accurate emulator, hardware requirements can be moderate. If you have a 32-bit ARM device, please do not expect the emulator to perform well - you will need at least a 1.5GHz CPU for good performance.

**For high upscaling (more than 2x) you will need at least a mid range device. This is because of how many pixels the emulator needs to render/shade - it is not a question of optimization.**

Game compatibility list:


1. Install and run the app for the first time.
2. Add game directories by tapping the add button and selecting a directory. You can add additional directories afterwards by selecting "Edit Game Directories" from the menu.
3. Tap a game to start. When you start a game for the first time it will prompt you to import a BIOS image.

If you have an external controller, you will need to map the buttons and sticks in settings.

Great! The latest update has lost my saves though. Following the instructions I get a message saying that no importable files were found. HUGE bummer there. I can see the files. The app can see the files. Not sure what is wrong or where to manually move the files too. Going to try to move them, delete the folder, create a new save, then move them to wherever the new folder is. I guess. Hopefully that works. Edit- It didn't work. Where are the New version files being saved?

-From Pixel4a running Android 11- For an emulator, it runs both 2d and 3d games really well, if the rips are good. When adding enhancements like resolution scaling and antiailiasing, most games will look better. It is recommended to play with a controller hooked up for a better experience, but they do have a touch screen layout as a last resort. At the moment, they do have a rewind binding, but no setting for the rewind itself. The app is constantly updated, so it's very up to date.

The code for rewind is all there, it's just not exposed in the Android UI because I'm concerned people would try to use it on too low-spec devices and then complain about performance. Maybe I can make it a hidden option somewhere in the future.

Definitely one of the better PSX emulators. It has handled every BIOS I've used on it with no problems. It has, also, run several patched ISOs without crashing, too. Edit: the update definitely did this app dirty. It's not totally unplayable, but it's not good any more, either. I get that you'd have been unlisted without switching to API31, but still...
